What are physical properties and why are they important to the design of a product? | The material it is made of, its mass, density, etc |
What advantage do Computer Aided Design and Drafting (CAD) provide over traditional paper and pencil design? | The advantage of CAD is that it is easily modified, and reproducible. Usually faster to produce. Can be looked at in 3 dimensions and seen at different angles |
How does the material chosen for a product impact the design of the product? | It determines the products weight and density, its durability, etc. |
What advantages do CAD sketches have over freehand sketches? | It is usually faster to produce and more accurate. Can be looked at in 3 dimensions and seen at different angles |
How is a geometric constraint different from a numeric constraint in the inventor program? | Geometric constraint "bonds" two geometric parts (surfaces, edges, centers) together (i.e., mate, flush). A numeric constraint is a measurement or distance and constrains an object to be a certain length. |
Acute Triangle | A triangle that contains only angles that are less than 90 degrees. |
Center of Gravity | A 3D point where the total weight of the body may be considered to be concentrated. |
Centroid | A 3D point defining the geometric center of a solid |
Tangent | A straight or curved line that intersects a circle or an arc at one and only one point. |
Circumscribe | A triangle located round a polygon such as a circle. To draw a figure around another, touching it at points but not cutting it. |
Principal Axes | The lines of intersection created from three mutually perpendicular planes, with the three planes' point of intersection at the centroid of the part. |
Density | The measure of mass density is a measure of mass per volume |
Volume | The amount of three-dimensional space occupied by an object or enclosed within a container. |
Inscribe | A shape drawn inside a circle. To draw a figure within another so that their boundaries touch but do not intersect. |
Obtuse Triangle | A triangle with one angle that is greater than 90 degrees. |
Fillet | A curved surface formed at the interior intersection of two or more surfaces of an object |
Right Triangle | A triangle that has a 90 degree angle. |
What 3D CAD functions could be used to create a wire paper clip? | Spline |
What feature would be used to create a 3D representation of a baseball or softball bat that was created on a wood lathe? | Revolve |
What do you need to know in order to perform a physical property analysis? | What material it is made of and dimensions of the object. |
Why is it important to perform a physical property analysis prior to producing a part? | In order to find the weight and density |
Why is it important to understand the mathematics used in physical property analysis? | The Mathematics is important for you to determine the volume, density, mass, weight and size of the object you are developing. |
